Introduction
Velux windows are known for transforming lofts and upper-floor rooms with natural light and ventilation—but their benefits don’t stop there. When specified and installed correctly, they can also contribute significantly to improving the insulation and energy efficiency of your roof. For homeowners in Burntwood and across the West Midlands, Velux windows offer a smart blend of style, comfort, and performance.
At Burntwood Roofing Repairs, we help clients get the most from their Velux installations—not just visually, but in terms of heat retention and overall roof performance. Here’s how to make Velux windows work harder for your insulation.
Key Takeaways
- Modern Velux units offer excellent thermal glazing technology
- Proper installation and accessories prevent heat loss and draughts
- Integration with surrounding insulation is crucial for performance
- Professional fitting guarantees airtight, long-lasting results
1. Choose High-Performance Glazing Options
Velux windows now come with advanced double or triple glazing, often with features like low-E coatings and argon gas filling. These technologies help:
- Reduce heat loss through the glass
- Reflect interior warmth back into the room
- Lower heating bills without sacrificing natural light
Opt for glazing designed for thermal insulation to enhance comfort during the colder months.
2. Use Insulated Flashing Kits
Flashing isn’t just about waterproofing—it also plays a role in insulation. Velux’s BDX kits include pre-installed insulation collars that close gaps around the frame and limit thermal bridging.
This creates a tighter seal between the window and the roof, helping to prevent unwanted heat escape.
3. Incorporate Vapour Control Layers
Moisture management is crucial in insulated roof spaces. Including a vapour barrier when fitting your Velux prevents condensation build-up, which could otherwise degrade insulation and promote mould.
This is especially important in kitchens, bathrooms, or any loft spaces with high humidity.
4. Blend Seamlessly with Roof Insulation
Installing a Velux should never mean disrupting your existing insulation. Our team ensures that the window is fully integrated with loft or rafter insulation, keeping cold air out and warm air in.
Poorly insulated reveals around roof windows are a common heat loss point—professional installation closes these gaps properly.
5. Add Thermal Blinds
For an extra boost in winter and summer, consider Velux thermal blinds or blackout blinds. These not only enhance privacy but also offer a layer of insulation, helping to:
- Retain warmth in colder months
- Block excessive heat during warmer periods
- Support year-round temperature control
They’re an easy upgrade that complements the window’s performance.
6. Ensure Expert Installation
Even the most advanced Velux unit can underperform if not installed properly. An incorrectly fitted frame or missed seal could result in draughts, leaks, or insulation gaps.
